88 BEPORT OF NATIONAL MUSEUM, 1923. 



Lyell limestone forms the crest of the ridge. The section includes 

 the Ozarkian Mons formation down to the Lyell formation of the 

 Upper Cambrian. Collections of graptolites were made from the 

 Silurian limestones in the upper portion of Sinclair Canyon, above 

 Radium Hot Springs, British Columbia, and lower down the can- 

 yon, thin bedded gray limestones yielded fossils of the Mons forma- 

 tion not unlike those so abundant at the head of Clearwater Canyon 

 and Glacier Lake to the north. 



Dr. R. S. Bassler spent two weeks of July, 1922, and the month of 

 June, 1923, in continuation of geologic work in the Central Basin of 

 Tennessee, begun two years ago under the auspices of the geological 

 survey of that State. The mapping of the Franklin quadrangle in 

 the western part of the Basin was completed, and work on the Wood- 

 bury and Hollow Spring quadrangles, on the opposite eastern side, 

 well advanced. Collections of carefully selected fossils and other 

 necessary data for the reports on the geology of these regions were 

 secured. 



During May, 1923, Dr. Charles E. Resser accompanied Dr. E. O. 

 TJlrich in an investigation of the Cambrian and Ordovician rocks 

 of the Valley of Virginia, and secured important stratigraphic col- 

 lections. Doctor Ulrich, with his assistant R. D. Mesler, continued 

 field researches during the month of June, studying various sections 

 of the Appalachian Valley in eastern Tennessee. This work was 

 under the auspices of the United States Geological Survey. 



Doctor Ulrich represented the Smithsonian Institution at the In- 

 ternational Geological Congress held at Brussels in August, 1922, 

 and during the trip visited important Paleozoic localities in various 

 European countries. All of the material collected was presented 

 to the Museum. 



"V\Tiile traveling in Europe in the summer of 1922, Miss Jessie G. 

 Beach was detailed to study collections in various museums, and to 

 consult with European scientists regarding matters of interest to the 

 xMuseum. Miss Beach reports visiting museums in France, Italj^, 

 Germany, Belgium, England, and Scotland, where she listed and 

 sketched various type specimens of unusual interest, and studied 

 methods of installation and labeling. Her observations have proved 

 of assistance in the work of arranging and labeling the National 

 collections. Conferences were held with Ferdinand Canu, at Ver- 

 sailles, regarding his studies in collaboration with Curator Bassler. and 

 with E. A. Walford, at Banbury, England, to perfect arrangements 

 for the gift by him to the United States National Museum of his 

 large collections of foreign fossils, as noted elsewhere. 



C. W. Gilmore, under the auspices of the Museum, made a trip to 

 Roy, N. Mex., to investigate a reported discovery of Eleplias re-
